TO ALL WHOM IT MAY CONCERN:

Be it known that I, EDWIN A. Dunn, of Decatur, in the county of Macon, and State of Illinois, have invented a new and useful Improvement in Hominy and Pearling-Mills; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will'enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification,,in which- Figure 1 represents a longitudinal vertical elevation, and

Figure 2 represents a vertical transversesection on theline a: a: of fig. 1.

Similar. letters of reference indicate corresponding parts.

The object of this invention is to provide a cheap and simple apparatus for preparing hominy, and for pearling barley, rice, and other similar grains. i

. It consists in a rotating shaft, provided with heaters, arranged to rotate in a horizontal cylindrical case,

to which the grain is fed by suitable mechanism, and from which it is passed away through a fan and a separating-screen, as will be more fully described on reference to the accompanying drawings, wherein= A represents a franie, on which is arranged the horizontal cylinder 13, in which the shaft 0 is arranged to revolve, which is.provided with the heaters or ,hnivcs a a, arranged thereon in spiral rows, for feeding the grain along in the cylinder at the same time that it is beaten by the knives. The cylinder is provided with a longitudinal rccess, D, opening'to the interior. of the cylinder in the top, against which the grain to be operated on istthrown by the rapid action of the heaters, and which arrests the tendency of the same to be carried around with the heaters, thereby efi'ccting a more perfect action of the beaters on the same.

E'reprcsents a hopper, arranged on the top of the frame, and provided with a shoe, F, which receives vibratory motion from the rod G, pivoted to the frame at g, the lower end of which is actuated by knockers on the end of the beater-shaft. t

I-I represents a trough, into which the grain falls, and which is provided with a conveyor, fixed to the shaft 0, whereby the grain is fed into the cylinder to be operatcdon by thebeatcr.

I represents a diaphragm, arranged in the cylinder, near the discharge-passage for the grain, which is designed to obstruct too rapid passage of the grain from the cylinder. It is provided with an opening, through which a passage is eli'ected for the grain by the said arms. 7 I d The cylinder is provided with a passage, K, for the discharge of the grain into'the air-chamber L, and with a slotted sliding gate, M, which may be adjusted to regulate the'fl ow of the same.

N represcnts a fan, for separating the chaff from the grain, and is operated by a belt from the shaft 0.

0 represents a curved chute, for directing the air to strikc the descending current of grain near the point of egress from the cylinder, which is arranged to be adjusted to regulate the blast from the cylinder as the grain passes through the spout P to the screen Q, where it is separated as may be required.

I am aware that most of the devices herein described, taken sepauately, are, of themselves, not new; but

What I claim, is The combination and arrangement of the cylinder 1%,hav'ing recess 1), diaphragm I, passage K, and slotted sliding gate M, rotary shaft C, provided with heaters a, rotary screen Q, fan-blower N, deflector O, chutes It I, hopper E,'vibrating-shoe F, and conveyor on shaft 0, all substantiallyas herein shown and described, for the purposes specified.
